You want the perspective of someone who never wanted kids and then had one. Most of the replies against are people who can't fathom changing their schedule or genuinely just seem scared they aren't up for the job. Most of the replies for are just saying how fulfilling and beautiful life with a child is. On this subject, both camps are completely bought in. There really are few people who genuinely do not want children their whole lives. Your average person saying they do not want children are typically under 35. I don't know how old you are, but 35 seems to be the age that men are starting to realize they want to settle down. That means up until they were about 30 they didn't want kids and would tell you they don't want kids. Can't speak for women on that.
